; Fig. 1 diagrammatically shows a printed line I number of letters or characters is to end at the gauge line II, then in making the second printing the line must be shortened for the distance a; i. e. the line must be compensated.

This amount aof compensation, as will be explained later on, is uniformly distributed over all the feed movements of the line by the device according to the invention and each feed movement will be shortened for a corresponding small amount so that upon the second printing, the line I having the same number of letters or characters it had with the first printing, will exactly fill the space between the gauge lines I and II. V a 1 Line 3, due to its contents, results upon the first printing, in a line which is shorter by the amount a than the desired length, and therefore, must be extended or lengthened by this amount a when making the second printing if the endof the line is to coincide with the gauge line II. According to the invention, the

amount a or compensation is, as will be explained later on, uniformly distributed over thev individual feed movements of the line and each feed movementof this line will be lengthened for a corresponding small amount, so that in the second printing the line 3 having the same number of characters or letters, is extendedor lengthenedior the amount .a and willend at the gauge line II.

The same is true for the lines 5 and I which have a greater length determined by'a corresponding adjustment of the device for setting the margin. This desiredlength of line is indicatedby the gauge lines III and IV. In these longerlines 5 and I the amount to be compensated, i. e. the amount a, for which, in the second printing, the line 5 is to be shortened and the line 1 is to be lengthened or extended, is distributed over a greater length. of line. having more feed movements. It is, therefore, evident that with the same amount a of compensation a smaller amount of displacement for I each feed movement is required when writing the long lines 5 and 1 than when writing the relatively short lines I and 3, respectively.

In the examples subsequently to be described, the invention is explained in connection with a simple typewriting machine. of usual construction in which a paper carriage iii isrdisplaceably guided upon rails l2 providedon the frame 9 of the machine. The printing mechanism, in

the present case, type levers 293 driven by key levers 20!, is mounted in the machine frame 9 9 (Fig. By depressing one of the key levers 7 2! the corresponding type lever 2% is swung and' the letter or character carried by this type lever is printed upon the paper arranged around the platen 292. A shoulder 203 of the type lever acts upon a universal bar 264, whereby, by way of intermediate members 2&5, 2%,

201, a paper carriage escapement device is actuated. The latter consists of a feed member 288 which, by means of a stationary and a movable pawl ZIQ and 2! l, respectively, alternately engages with the teeth of a ratchet wheel ZiZ.

, If one of the type levers Eilil is moved out of its position of rest shown in Fig. 5 into the printing position and back again, the feed member 208 is once swung to and fro about its axis 209, whereby the ratchet wheel M2 is released to be, rotated one tooth pitch. This rotation is effected under the action of a device for drawing the carriage, for instance, a spring not shown in the drawings, and tending to always draw the paper carriage ii! in the direction of the arrow B (Fig. 2) which, ratchet wheel 252, however,'by the above described escapement device 208-2l I, is prevented from effecting such rotation in the position of rest. Therotary movement of the ratchet wheel 2E2, when released by theescapement device 2Eil32il, is transferred to the paper carriage. It] by means of a gear wheel I4 coupled to the ratchet wheel and a rack bar i3 engaging therewith and mounted on the paper carriage" it, so that during rotation of the ratchet wheel M2 for one tooth space, the paper carriage ii! performs a feed movement corresponding to the pitch of the character or letter. Such a feed movement may also be effected without printing a letter or character by actuating the so-called space bar Hit, the rear end of the key lever 2M of which also acts upon thefeed member 2% and allows the above described reciprocating swinging movement of the feed. member 268 without simultaneously operating 'a type lever.

' The invention is not limited to this kind of machine, and may also be used where type wheels or othercarriers for characters or letters are employed. The invention may also be used if the printing movement of the carrier for the characters or letters is effected not by hand, but by some suitable power drive controlled by templets or perforated cards, or in any other suitable manner.

Finally, the'inventio-n may also be used if, during printing, the printingmechanism is moved step by step and the paper support is stationary.

In the construction according to the present invention, the rack bar !3 is not rigidly connected to the paper carriage IE, but the latter and the rack bar l3 are relatively movable in a longitudinal direction. This shifting in the longitudinal direction is permitted by the 'pin-and-slot guides i611! shown in Figures 2 and3 provided at both ends of the rack bar l3 and-by a sleeve l9 connected to the rack bar l3, and guided upon a guidebar is rigidly connected to the paper car- 'arm' of a bell cranki'leverli-li The bell crank tain thelocking tooth 55 iniengagement with the ratchet,whe'elv53;v The knob 55 arranged atthe front of rthe machine, is provided with gf'aduations, extending,- for instance-on the one forms an actuatingmember for obtainingalongitudinal movement ofv the paper carriage l rela tivelyto the rack bar [3 uniformly controlled bythe escapement devicezZOE-Z l2. The bell crank lever 23 is pivoted at 25 to a member 25 rigidly connected to the paper carriage H); A guide roller 25 is mountedattheiend of the'other arm of the hell crank lever 23, the guide roller 26 being accommodated ina rail'ZT of U-shaped cross sec-1 i This rail 21 serves'for controlling the loii'gi tudinal displacement of the paper carriage III with regard to the rack bar l3 as efiected by' the actuating member 23. 27 is supported by two bolts 26 and 29iarid is prevented from undesiredidisplaceme'nt in the lon gitudina'l direction by thebolt 33 sliding in a vertical guide 34 of a member 35 seciiredto'the' frame 2 of the machine; The bolts Z3 and 29 engage a longitudinal slot of the rail 21 and may be adjustedalong this slot as desired. Of course, a longitudinal'slo't may he provided in the rail 2] for-each ofthe' bolts28 and 2S, r'e spectively. These bolts'iB and 29 have fiat heads which prevent the rail 21 from slipping on the bolts. A

For this purpose the rail The bolts 2c and 2a supporting'the rail 21 are connected to the depending arms 3! and 32, re-

spectively, of the means for settingthe margin. 1

As shown in Figures 2 and 4 these depending arms and 52 for setting the margin preferably are adjustable along a bar 35 provided with aseale and mounted on-the frame 9 of the'niachine iii' such a manner that the' depending arms may be shifted in either dildtion Of niovemen'tof the carriage. To fix the depending arms 3| and 32 for setting the margin in various positions of adjustment upon the bar 36, locking'devices 40 and 35,, respectively, are provided whih may be engage'dwith or disengaged from the serrated lower edge of the bar 36. c The bolt 28 isdir'ectlv fixed to the depending arins 31 for setting the margin. The bolt 29, howeven'is connected to a slide member M which is guided in ave'rti'cal direction the fingers 32 and 43 of the depending arm 32 fo-r'settin g the margin. The bolt'm, moreover, is guided in a horizontal slot 'oi a setting member which; according to the construction shown, is formed as a skeletonized plate 55. The plate 55 is mounted for vertical movement relatively tothe frame 5 by pin a'nd slot guides to. Arranged on the plate 45' is a: vertical rack bar flengaging a gear wheel48 journalled in'the frame of the machine. Pref-5 eraoly, the gear wheel es is rotated by means of a setting member from thefront side of the.

machine.

'Fixed to and mounted co-axiallv with the, gear wheel 48'is aratchet Wheel 53, the number of teeth of which corresponds tothat of the teeth of the gear wheel 48. -A locking tooth 56 of a pawl pivoted at '54' cooperates with'tlie ratchet wheel 53. A spring" 51 tendstomain As may be seen from Fig, 5, this set-a ting member preferably isformed as a rotatable scribed above.

' for one pitch corresponds to a rotation of the ratchet wheel 53-and of'the gear wheel 48, aswell as aliftin'gorlow'ering of the rack bar 4'1, for one pitch. The inclined faces of the teethadf the ratchetwheel iil cause the locking tooth 55 of the pawl 55' tonbegforced outof a space between two teth ofthe :whee153 against the action of the spring 151 and, moreover, cause the pawl 55 to be rotated in an anti-clockwise directionlsee' Fig. 2) Owing to this rotation a second locking tooth 58 of the pawl 55, engaging a rack bar 55!; is disengaged. The" rack bar 59 is fixed to the plate 4530 that upon engagement ofthe look ing tooth 58 withsuch rack bar," displacement of the plate 45 in an upward direction is impossible and adis'placement in a downward dir'ec tion is domparativelydifiicult. The teeth of the rack bar 59 areisoconstructed that theyhave upwardly directed horizontal flanks and downwardly directed inclined flanks.- The pawl 58, however, is providedwith a horizontallower'face and anv inclinedupp'er face; If an attempt is mad to move the plate 45 upwardly, the horizon tal upper flank of a tooth of the rackba ris caused to bear against the horizontal lower surface of the locking tooth EBQthereoy preventing v an upward movement of the plate 45. Upward movement is rendered possible only if the locking tooth 58 is disengaged in the manner dewardly, the inclined lower flank of a tooth 59 of the rack bar cooperates with the" inclined upper flank of the locking tooth 53, whereby the latter, against the action of'the spring 5?, is

forced out of the teeth of the rack bar 59 as soon i as a sufiiciently strong pressure is exerted upon the plate 45' from above.

This construction of the locking for the upward and downward 'movement, re-

spectively, or the plate 45 has the purpose of aband therewith also the fulcrum 24 and the fulcrur n 22'of the bell crank lever 23, in the direc tion of the arrow B The fulcrum 22, however, is, due' totheconnection 2! 20, [9,13, i4, prevented from such a displacement by the escapernent device 2fl8 2l2 of the pap-er carriage so that a torque is' formed which tends to swing the bell crank lever 23 man anti-clockwise direction' (see Fig. 2). This swinging movement of the lever 23 is prevented by the guide roller 25 engaging theupper flange or the rail'Z'l of U- shaped cross section. An undesired displacement of the rail 21, however, is prevented by the above mentioned locking" device 58, 59. Downweirdly directed pressure is not eiie'r't'ed upon the rail 21 and, therefore, not upon the plate 45, so that the 1ocking o'r Safety dviceTneeds onl-v to prevent uhdesired downward movement of the plate 45 diieto' snoeksi vibraoons and the like The" rack bar 47 is mounted on the plate 45 by means Of th plH-aiid-sIOt c bfinefioiis 6D and If the plate 45 is inoveddownarrangement tively to the rack bar [3.

ting knob 55 is turned so that the gear. wheel 48 is rotated in the directionof thearrow. c (Fig. 2); then the rackrbar 41 is moved upwardly along theplate 45 against the actionrof; the spring 6|, because the plate 45 is still locked by the-locking pawl" 55, 58. During this displacee ment of I theirack the ratchet Wheel 53 maybe rotated far enough to disengage the locking tooth 58 from the rackbar 59by swinging the pawl 55 in an anti-clockwise direction. The slots of the pin-and-slot connections 69 are sodimensioned and the springjtl is so strong that in spite of the possibility of mutual displacement ofthe rack bar 41 and the plate 45, an exact and reliable movement ofqtheplate45 by thegear wh'eel 48 is ensured after the locking pawl 58, 59 is disengaged. As soon as the gear wheel 48 is rotated one tooth thelockin'g tooth 56 of the-pawl 55 engages the next tooth space of the ratchet wheel 53, which enables the pawl 55 to rock in a clockwise direction'so far that the locking tooth53 also engages the rack bar 59,

'thus again locin'ng the plate 45 against displacement ina vertical direction.-.

By the displacement of the,.plate.45 in:a vertical plane, the boltv 29 isflraisedor lowered,

whereby thev slide M is moved up and'downbetweenthe arms 42' and 43 of the depending arm 32 for setting the margin, and the control rail. 2'! is rotated about the fulcrum formed by the. bolt 23 ofthei depending or fulcrum farm .3I for setingithe margin and adjustedin various inclined positions. .3 7

If, for instance, the control rail 2'! is brought into a position inclined upwardly from the ful- 'crum bolt 23 to the bolt 29, then ateachfeed length, the turning movement of the bell cranl;

lever 23 may cause a displacement of the paper carriage ill with regard to the rack bar E3 of, the carriage only. This results in a displacement of the paper carriage Ill relatively to the rack bar IS in the direction of the arrow (1, i. e. to increase by a fixed increment, each of the feed movements of the paper carriage lB-rela- A position of therail 21, inclined downwardly from the fulcrum bolt 28to the bolt 29, therefore, efiects adisplacement of the papcr care riage it! with regard to the racl; bar it in the direction of the arrow e, i. e. resulting in a" shortening of the individual feed movements of the paper carriage l0 relativelyto those of the rack bar it. By adjusting the control rail 2? into various inclined positions by'means of the setting knob 50 longer or shorter feed move- .ments of thepaper carriage I!) may be obtained the adjustment of the depending arms 3! and- 32 for setting the margin upon the. gauge lines I and II, respectively. In order toshorten the line- I, for instance, for the distance a, the control rail 21, in accordance with the above explained'operation, must occupy a position inclined downwardly from the fulcrum bolt 28 to the bolt 2:) which is indicated in Fig. 1 by the distance line 2. The bolt 29, therefore, must be lowered for a corresponding amount a from the position illustrated. In order to extend the line .of text 3 about the amount a, the control rail 2? must occupy :a position inclined r cordance; with the sine of the. angle.

upwardly from the fulcrum bolt 28 to the bolt 23, This position is indicated by the distance line t in the upper portion of Fig.1. To obtain this position, the bolt 29 must be lifted by the corresponding amount a from the centre position shown in .the drawings. By this downwardly or upwardly inclined position of the guide rail 2-! shown by the distance lines 2 and respectively, the length of each normal letter spacing step to be transmitted from the carriage. feed'rack is to the paper carriage ill, is increased or decreased by an equal amount from the beginning of the line of text, indicated by the gauge'line I, to the end of such line, indicatedby the gauge line II. The amount of the additional movement depends on the degree of inclination of the control rail 2?.

- Preferably, the arms of the actuating lever 23, transferring the control movement from the rail Z'l to the paper carriage, are of equal length so that the amount of the additional displacement of the paper carriage corresponds to the amount of upward inclination of the rail 2'. over the portion of the longitudinal movement of the paper carriage in consideration, that is, in ac- In this manner the amount by which the control rail 2! is to be lifted'or lowered, respectively, may be maintained exactly equal to the amount 'by which the lines of text are to be lengthened or extended, or. shortened, respectively.

From a considerationof Fig. lit is to be seen that for compensating the longer. lines 5 and in which the depending arms 3| and 32 for setting the margin are adjusted along the supporting bar 35 according to the gauge lines III and IV, respectively, and in which the bolts 28 and 29 occupy the positions 28- and 29', respectively,,a smaller inclination of the control rail 2'! results if the bolt 29 is adjusted upwardly or downwardly, respectively, by the same amount of? The corresponding downward and upward inclination, respectively, of the control rail is indicated in Fig.1 by the disk lines 6 and 8, respectively. It may, therefore, clearly be seen & that with longer lines of text a smaller additional movement of the paper carriage at each feed movement is required to effect compensation of the same distance a.

' For lifting or lowering the control rail 37 from the horizontal position shown in Fig. -l by the line 5, respectively, the bolt 29 is lifted or lowered, respectively, in the manner described, by the plate d5. This is 'effected'by actuating the setting knob 50. If, in the individual lines of I text amounts differing from each other are to be compensated, i. e. if; for instance, the first line is to be shortened for two character or letter movements, the second line is to be shortened for three character or letter movements, the third line is to beextended or lengthened for four character or letter movements and so on, then, of course, in each individual line a corresponding lifting or lowering, respectively, of the bolt 28 and therewith of the control rail lengths of lines of text as explained in connection with, Fig. 1 automatically results from the adjustment of the bolts 28 and 29, supporting the rail 21, in the slot 30 during adjustmentof the depending arms 3 l, 32' for setting the margin.

By the adjustment'oi; the depending arml-for setting the margin and, therefore;- by the adjust.- ment of the boltZB, the fulcrum of'thc guide rail 21 is allteredwhereas by-the adjustment of the depending arm 32 for setting the margin and, therefore,- by the adjustmentof the bolt, 25; the position of the point of applifl tion of the force for lifting or lowering the rail '21 is altered: The

position into the position Ti-i? effects rotation of the gear wheel 48 in the direction of the arrow for one tooth, whereby the plate 4; and bolt 29 also are lifted by thispangu lar amoun and the. rail 27 is adjusted upwardly. by the amount mentioned, from the bolt 28. clination of the rail causes a lengthening of a line for one character or letter. Therefore, with adjustments of the setting knob 50 $9. the gradu-v ation lines +1, +2,v +3, +4, +5, +6 lengthenings, of the lines to be justified for amounts of 1, 2, 3, .4, 5, or 6 characterscr letters are effected.

By adjustment of .the setting knob 9 upon'the graduation lines -l, -2, 1-13, 4 however, shortenings of the lines for 1, 2, 3, or .4 characters or letters are obtained. Of course, another distribution of the graduations on. both sides of the graduation line .Bi may be provided depending upon the desired range of justification.

F r si na i t e set in arrows .Q W9 i maybe provided upon the knob 50 instead of the signs and The arrangement is such that in the position n wh c he p p c ia e a he beginnin 9 a line, asa n acc r spcndin sto $0 the depending arm 3 for setting the margin, the guide roller 26 of the actuating lever 23 comes into the range of the bolt 28; Qf speciala dyanr is a a e n accord n t wh ch in the above, m nt ned ta t naroeiti e th paper a e the 1 1MB and h ro a e s bolts 28 and 29 are so positioned withregard to o the depending arms 3| and 32, respectively, for

positioned with regard to each other as tooccupy one and the same vertical plane thatrfollor 26 and the .bolt 28 lie in axial alinement. The

importance of this arrangement will be explained indetail when the mode of operation of the device according to the invention is described. I

At the first printing of a document-thesating knob is adjusted to the zero position, i; e. the control rail 21 is brought intoalhorizontfal .po sition (Fig.2). The paper carriage wand the rack bar I 3 are permanently .maintainedii tiie same relative position during operation or the m ch n b u e o l 2.7. @Edifi Z l ?%i1 -23 ar n t d ed by as ra .z idur n th tr e e th r re arr a e.

I I When the first printing "is f nished then at the second justified printing, the setting knob is, before starting the printing of each line', brought into the position which is indicatedloy the mark printed at the end of the corresponding line of the first printing, whereby the above described setting operations arecarriedout and shortening or lengthening of the line by the desired amount is rendered possibleQIDuring this adjustment at the start of a line, the paper carriage comprehend the [effect of this adjustment, suppose that, in the starting position of the paper carriage the roller 26 should occupy a position somewhat to the left ,or to the rightoi thebolt 2.8 (Fig. 2), then on swinging the'rail during adjustment to the amounts of justification'at the beginning of eachfline, th roller 2% would be lifted or lowered and therebythe paper pee riage 1'0 would be displaced with regard to the rack bar l3. Since generally, when making a jus tified printing, .an adjustment of theguideraii 2] is required for each line, the mentioned resulting displacements of the paper carriagefid with regard to the rack'bar l3 at .the beginning of the line also would be different for each line, so that a uniform left hand margin of the document could not be obtained. V

" To" facilitat reading 'off the justification amounts for each individual line the device shown in1Fig. .7 may, for instance, be used. Along the line scale 10 of themachine a short scale 12 may be shifted and fixed in any desired position or adjustmentlwith regard to the scale V 10. The scal 12 carries a small pointer hearing the markY O. At one side of this mark a graduat o from to treat the ign lineso f the scale 10. Before startingithe first,

'i. e the non-justified printing, the pointer '13 of the short scale 12 is adjusted to the graduation line of the line scale 70 which corresponds to the desired justified end of the line.- In Fig. 7, this is the graduation line '75 or the scale it. if-the carriage pointer H, after printing the last character or letter of a line, stops in the position shown in Fig. '7, then it points to the graduation line +2 of the short scale 12. This mean -that the line just printed is shorter by the amount of two characters or letters than the desired length of the justified line and, therefore, is to be lengthened by the amount of two characters or letters when making the second justified printing. The provision of the scale 12, therefore, renders superfluous the counting or calculating of the amounts of justification necessary for each printed line and assists in obviating mistakes.

As the exact and reliable ascertaining of the amounts of justification during the first printing is of special importance for obtaining the justified second printing, a particular advanta e is to be considered in a further improvementof the device according to the invention, by means of which these amounts of justification are automatically recorded by the machine at the end of the individual lines of the first printing. This record, therefore, is efiected independently of the attention and the exact operation of the operator. The additional improvement consists in the device shown in Figs. 9, 10, 11 and 12.

Adjacent the conventional type guide as a series of resilient tongues 8| is provided on the frame 9 of the machine, the upper ends of which,

facing platen 82, carry numeral or digit types 33.-

In the construction shown, the first" four types from the left (Fig. 9) and from the right (Fig. 12) respectively, are provided with inclined numeral types 4, 3, 2, I. rangement of the numeral types 83 on the tongues 81 in an elevation shown in the direction of th -arrow D in Fig. 11; The fifth'tongue B! from the left (Fig. 9) and from the right (Fig. 12), respectively, carries the cipher and the following types to the left, Fig. 12, carry vertically arranged numerals 1.to 6. By means of a sleeve 89, a cam 88 is mountedto be slid along the paper holding rail 64, which is swingably mounted in the paper carriage frame by means of arms 85, 86 and a sleeve 81. The sleeve 89 carries a resilient indexing tongue at, which presses against the upper surface'of the paper holding rail 84 and holds the sleeve 89 and the cam 88 upon the paper holding bar 35 in any of its adjusted positions. indexing tongue 90, Fig. 10, also serves as a pointer cooperating with the graduation provided upon the paper holding bar 84. This bar 81!, is journaled at 91 and 92 in swinging arms 85 and 86. One end of the bar 84 extending beyond the swinging arm 85 carries a crank 93 provided with a crankpin 94 with which cooperates an arm as of the feeding lever 96 of the machine. Adjacent the crank 93 a spring 97 is provided which tends to rotate the paper holding bar 84 into the posi-' tion shown in Figs. 9, l0 and 11. In this position, the cam 88 occupies relatively to the platen 82, the position shown in full lines in Fig. 11. Further rotation of the cam 88 towards th platen 82 i may be prevented by a stop limiting the rotation of the bar 84. Ifthe line feeding lever 96 is actuated, the extension 95 strikes against thecrank pin 94 and rotates the crank 93 and the paper holding bar 84 against the action of'the spring The endof the resilient Fig. 12 illustrates the ararrow 2: (Fig. 11) When occupying a position in the range of any of the resilient type-carrying tonguesgl, the end 98 of the cam as presses against the upper end of one of these type-carrying tongues and bends its free upper end-away from the platen until the end 93 of the cam 88 slides off the end of the flexed 1esilient, type-carrying tongue 3%, whereupon the latter springs back and strikes itstype 83 against the platen 82. All the resilient; type-carrying tonguest8l are connected with, a rail 99 which, by means of arms Hi0 and ml, is swingably mounted at H12 and I93 on themachine frame 9 and is held in a position in contact with the backs of "the resilient type-carrying tongues by means of a spring,- not shown in the drawings. The arm [Gil of the rail 99 has an extension IM which engages a member we of the ribbon fork 105. If, by flexing one of the resilient typecarrying tongues 8|, the rail 99 is swung in a direction away from the, platen, then the ribbon fork 105 is lifted by the connecting members i323, I04, I06 and the ribbon it]? is lifted so far as to occupy a position between the types 83 and the platen 82. If, now, the corresponding resilient type-bar 8! is releasedby the end of the cam 98 and springs againstthe platen e2, printing upon the paper surrounding the platen is effected by means of the ribbon ID! at a point spaced to the right of, and in line with the printed line of text. 01 course, instead of the above described device for lifting the-ribbon any other inking mechanism for the types 83 may be used, and which may b brought to action in the corresponding 'manner.

The device shown in Figs. 9,10, 11 and 12 operates in the following manner: 'On the first printing of a document to be justified or equalized, the end of the indexing tongue 99 is adjusted by shifting the sleeve 89 along the graduated paper-holding rail 84 to a position corresponding to the desired end of the line, for instance, to the graduation line 32 in Fig. 12. Assume that the position of the resilient typecarrying tongues 8! with regard to the printing point of the types and the position of the indexing'tongue fi -with regard to the tripping cam 88 are so chosen that the cam 88, after the printing of the last character or letter of a line of the first printing which, by chance, has the desired length, comes to rest just in front of the resilient type carrying tongue 8| carrying the type B. To be able to print the next line of the first printing, the paper carriage must be shifted back to the starting position in the direction of the arrow A (Figs. 9 and 10). This is effected in the usual manner by means of the feeding or line-spacing lever 96. The movement of the carriage and the feeding of the lines are effected by a single operation; The arrangement is such that, upon operation of the line spacing lever '95, its arm 95 first actuates the crank pin 94 to partially rotate the paper holding rail 84 together with the tripping cam 88 in the manner described above, whereby the corresponding type-carrying tongue 8| prints its type 83, in the example given, a E tothe 91 to swing the cam 88 in the direction of the right of, and spaced apart from the right hand end of the line. The zero at the end of the line then indicates that in making the second printing, the setting knob'5i! (Figs. 5 and 6) is to be adjusted to the graduation line B for this line. After printing of the type 83, the line feeding is effected by a further swinging of the lever 95, whereupon or simultaneously with the feeding of the line the paper carriage is shifted in the direction of the arrow A (Figs. 9 and 10); After 7 Without departing from the spirit of the inrelease of the feeding lever 96, the latter returns to its starting position shown inFig. 10 and the paper holding rail 84 is rotated b'ackwardly by the spring 9'! so that the tripping cam is returned from its swung out position 88', shown in dotted lines in Fig. 11 into the position of rest 88. As the next line of the trial or first printing is'typed, the paper carriage is moved towards the left, and the tripping cam, at the end of the line, again occupies a position between the platen 32 and the type-carrying tongues 8I. Depending on whether the lines of the first printing are, for instance, shorter by the amount of two characters or letters, or larger by the amount of'four characters or letters than the desired length of justification, the tripping cam 88stops at the end of this line in front of the resilient torque 8I carrying the even type numeral 2, or the typecarrying tongue bearing the rearwardly inclined type numeral 4 (Fig. 12), and in the manner de scribed above, prints this numeral incident to the operation of feeding the line. In this manner the automatic printing of the amountsof justification is effected without the operator being compelled to count the required-increments of justification, to calculate them, or to read them off a scale and write them down.

Of course,instead of arranging thenumeral type at the right and left or". the it position (Fig. 12) in various inclined positions, other discriminating marks also may be introduced to indicate to the operator the proper adjustment of the setting knob 50 for each line of the second printmg.

When making the second justified printing no characters should be printed at the end of the lines, as that would mar the appearance of the printing. Moreover, due to the uniform length of all lines the same character or'numeral would be printed which, in the present example, would be 6 because of the adjustment of the indexing tongue 99 on the rail 84 to The tripping cam 83, therefore, preferably may be rendered inoperative. This may be eifected, either by shifting the sleeve 89 to a point on the paper holding rail B l which, at the end of the line, is out of the range of the resilient type-carrying tongues SI, or by means of a device known per se, the paper holding rail 84'may be lifted from the platen 82 to shift the crank pin 94 out of the range of the arm 95, so that when feeding thelines no rotation of the paper holding rail 64 and, therefore, of the tripping cam 88 is effected.

Such a lifting device is shown in Figs-9 and 10. lhe swinging arm 85 carries a member I I I which, by means of a handle IIIl, may be swung about an axis arranged in parallel to the paper holding rail 84. A cam surface II 2 on the member I II bears at I3 upon the frame It) of the paper carriage. On turning the member I II in one direction the cam surface H2 causes swinging of the armed to swing the paper holding rail 84 away from the platen 32. Swinging of the member I I I in theother direction restores the paper holding rail 84 into the position shown in Figs. 9, l0 and 11 opposite the platen 82. To ensure that in both positions of the paper holding rail 84, the rollers 29 pressing the paper against the platen bear against the sheet to be'printed, the paper holding rollers I28 are, as shown in Fig. 9, journalled in arms I 49 of guide sleeves III to resiliently bear against the platen 82. Said guidesleeves I2I are adapted to be shifted along the rail 84 and re main in any desired position of adjustment.

the control rail 21.

vention it is, of course, possible to make a number of modifications different from the example described above. So, for instance,'the device for lifting and lowering the plate 35, instead of being operated by means of a .gear wheel and a rack bar, as shown in Fig. 2, be operated by means of curved guide members or eccentric devices shown in Fig. 8." Instead of the gear wheel :13, the curved disc 35 (Fig. 8) is used which is fixed to'the ratchet: wheel 53 and rotated with the latter. The curved disc I has an eccentric guide slot I3! into which engages a follower 232 provided on the "plate 45. The follower 32 used in this modification instead of the rack bar El according to Fig. 2, may, like the latter, be shifted in a vertical direction for a small amount. The follower N32 is guided by elongated holes I33 and is drawn into its lower position by a spring I34. lf'he other constructions and the operation of the device according to' Fig. 8 are the same as described with reference to Fig. 2.

In the machine according to Figs. 2 and fi, the.

arrangementfor setting the margin is provided at the rear side of the machine which results in a particularly simple connection to the guide rail fhe device according to the invention may also be fused in connection with machines in which the devices for setting the margin are not provided at the rear side of the maclnne. For such machines, the arrangerr'rent shown in Figs. 13, id and 15 allows a corresponding registering adjustment of the devices for setting the margin arranged at the front side of the machine and. of the bolts 28 and 29 holding the control rail 2?.

The two stops Mil and I4I for setting the margin are, in this case, arranged at the front of the frame Q of the machine upon a rack bar 42 and may be longitudinaliy displaced and fixed in any position of adjustment. Each of the two stops operate with a line scale M5 fixed to the frame 9 cf the machine above the rack bar 542. The

' stop M3 for setting the margin is linked by means of a connecting member 5 16 to an arm Ml fixed upon a shaft 548. The latter is journalled in the frame 9 of the machine and at the rear of the machine, carries' an arm i ls which also is fixed upon the shaft and is linked by means of a connecting member i510 to a slide member I5i (Fig. 14).- The slide member iEI is d'isplaceably arranged along the horizontal slot 4d of the plate and carries the bolt 29 supporting one end of Depending upon the position of the stop l '58 for setting the margin, the bolt 255 occupies a corresponding position in the slot 38 of the control rail 21. At the rear of the machine the slide member i52 is associated with, for adjustment by the stop it! for setting the marg The slide member M52 is displaceably arranged in a horizontal direction along the slot I53 of the plate 15-4 fixed to the frame 9 of the machine and carries the fulcrum bolt 28 supporting the other end of the control rail 2i. The rail Sal-carries, in a manner similar to that shown in Fig. 2, a bolt 33 which is guided in a slot 3 f. of the stationary plate ifi in a vertical direction and prevents undesired displacement of the rail 2'! in the longitudinal direction. The slide action of this spring a tooth- !58 of the pawl Hi5 engages a rack bar I59 which is swingably mounted at It!) on the stationary plate M6; 'The end. E of the rack baris provided with two steps and is supported by the end E62 of a lever IE3 pivoted at ltd to the frame 9 of the machine. A spring Hi5 tends to rotate the lever !53 in an anti-clockwise direction (Fig. to bring the end H62 into the position in which it holds the rack bar in the position shown in Fig. 13 against the action of the spring 555'. If the I lever M33 is rotated in aclockwise direction until it strikes against the abutment I'M of the.

frame Q of the maclune, the end 32 of the lever disengages from the lowermost step of the end ltl of the rack bar, whereupon the rack bar 59, under the influence of the spring. E55, is swung downwardly until the second step of the end Hit 'of the rack bar bears against the end EEZ of the lever, thus disengaging the rack bar lfit and the tooth I58 of the pawl, as the pawl E55, due to the action of the stop lit, cannot be swung further downwardly, as shown in Fig, 13, and, therefore, is not capable of following the downward movement of the racl; bar EEG. Theslide member H52 is urged towards the right (Figs. 13 and 15) by'a spring till, one end of which is connected to an arm 163 of the slide member 352, whereas the other end is fixed to the frame 9 of the machine. The engagement of the tooth I58 of the pawl 55 with the rack bar I59 prevents the movement of the slide member 552 towards the right (Fig. 13) under the action of the spring tell. when, as described above, the lever 163 is rocked counter-clockwise, the rack bar IE5) is swung downwardly, releasing the locking mechanism mentioned above and the slide member i542 is moved along the guide slot 53 under the action of the spring ltl, thus shifting the fulcrum bolt 28 along the slot 39 of the control rail 2?. To bring the slide member I52, and thereby the bolt 28, always into the position of adjustment which corresponds to the adjustment of the stop M! for setting the margin, a stop bolt N39 is provided on the arm of the actuating lever 23 carrying the guide roller 26, which stop bolt I69 cooperates with a catch lid pivoted at HI to the slide member 552. The arm H2 of the catch extends into the path of the stop bolt 59 and its other offset arm H3 engages beneath the rack bar i559. As clearly shown in Fig. 2, the actuating lever 23 is swingably mounted at 24 on a member 25 rigidly connected to the frame 9 of the paper carriage. If, during return travel of the carriage, the paper carriage and therewith the actuating lever 23 are moved in the direction of the arrow'A then the stop bolt I58 strikes against the end F52 of the catch ill] and on its further movement, drives the slide member I52 to shift the pawl l5? relatively to the rack bar I59. Finally the paper carriage strikes against the stop it! for setting the margin to arrest the slide member I52. The stop Ml for setting the margin and the slide member I52, particularly the bolt 28, then occupy corresponding positions. If, on adjusting for a new line,

the slide member !52 occupies aposition at the left of the stop id! for setting the margin (Figs. 13, 15), then the paper carriage, on its return travel in the direction of the arrow A, is arrested by the stop MI for setting the margin before the stop bolt I68 reaches the catch H2, H0 of the slide member 552. Due to the paper carriage striking the stop Nil for setting the margin in the direction of the arrow A, the rack bar I42, which may resiliently be shifted slightly in the longitudinal direction, is displaced in the direction of the arrow A. Duringthis displacement, a

Against the action of the spring the lever ifiii'is hereby rotated in a clockwise direction, the rotation being limited by the stop lid as mentioned already abovev During this rotation, the end lt-Z of the lever M53 is withdrawn from beneath the end Edi of the rack bar I59, whereupon the latter swings downwardly and the tooth i558 of the pawl disengages from the rack bar we. The slide member l52gnow moves under the action of the spring, IE5] until the end 5'52 of the catch l'ld strikes against the stop bolt Hereby the lever 51B is rotated in an anti-cloclo- .wise direction (Fig. 13) and the opposite, offset arm H3 presses from below against the racl:

bar E59 tc-rock the rack bar upwardly against the action of the spring 565. After thearrest of the carriage by the stop Mi for setting the margin, the lever E83 is released by the projection 686, the spring 565 rotates said lcverin such a manner that its end I62 engages again below the. lowermost step of the end H55 of the lifted rack bar 559 to maintain the. rack bar in the position shown in Fig. 13. The tooth l58 then again engages the rack bar Hi8 so that further movement of the slide member i522 by the spring I6? is prevented. The slide member E52, and therewith the fulcrum bolt 23 supporting the rail 27 is either shifted by the paper carriage into the position corresponding to the adjustment of the stop i l! for setting the margin, or said member, under the action of the spring itil, automatically springs into the desired correct position. The operator only needs to adjust the stop IQ! for setting the margin and to return the paper carriage in the direction of the arrow A into its starting'position.

To prevent idle running and vibrations, the paper carriage It andv the rack bar 63 may be connected by a special spring 5st, Figs. 2 and 5, in addition to the connection shown in Figs. 2 and 3 -co nsisting of the members 25, 23, 2E, 19. One end of the spring E96 may be fixed to a stud i552 on the sleeve 69 adjacent the sleeve 55 and the other end to a stud l 9i on the paper car- Owing to this arrangement, the spring i9 effects a dampening action between the relatively movable member 13 and ill.

As the device according to the invention, permits the adjustment of a writing machine to longer or shorter feed movements, the invention may also serve the purpose of easily and quickly adjusting the machine to various kinds of writing. If, for instance, a set of types is to be mountedin the machine whicheffects printing of broader characters and letters and. therefore, re-

quires correspondingly longer letter spacing feed justing the setting knob 553 (Figs. 5 and 6) in the direction of the arrow designated with and by bringing the rail 27 into an inclined position in the manner described above. a dispiacement of thepaper carriage ill relatively to the Irackfbar 83 may be effected which corresponds to the desired lengthening of the feed movements In a similar'manner it is possible toeasily and quickly change from a feed movement adaptediorzprinting larger :characters to one adapted,for printing smaller charace terse.

WhatIclaim'is: I

1. A device adapted to be used in connection with typewriting machines, including a paper carriage, and letter feed means therefor, means for varying the length 'of the letter feed movements of the carriage to justify the lines of writing to. a desired uniform length, an=actuating individual lines of the second printing are ascertained by means 'of' the first printing. 7 The device is always adjusted tothese lengths of justification before printing a line of the second printing. This adjustment is effected by means of thesetting knob 313,; the pointer-360 and the scale 3M. Theadjustment by means of the setting knob 3|3 alone, however, is not sufiicient to effect'the desired justification of the linesin each case." If for instance the pointer-360 is adjusted upon the number 3of the scale 3", then this means that a lengthening by the amount-ofthree ordinary character spaces is to be effected for the corresponding line. A line of sixty ordinary characterfspaces whichis to '-be lengthened by the amount of three such spaces evidently requires a greater inclined position ofthe guide rail than aline with ninety ordinary-character spaces which is tolbe-leh'gthened'by the same amount, because in the first case, the length of 'justific'a tion is to be distributed over sixty' character spaces, whereas in the second case, over ninety; The adjustment of the guide rail |-by thea'ctuation of the'setting knob'3l3', therefore, requires an adaptation'to the length of line in question which is effected by means of-th'e knob 3|2, the

scale dial 3I1-and'the pointer 365. The scale 3 I I has a-graduation corresponding to the various lengths of lines: In Fig. 19, for instance, asetting of a line of eighty ordinary'ch aract'e r spaces is shown.
